how do you calculate acceleration?

Question

how do you find acceleration? is it like distance over time... or distance times time... idk ...pleasee helpp!

Answer 1

Velocity is the rate of change of distance , V=d/t and acceration is the rate of change of velocity, v=vo+a*t rearranging a=(v-vo)/t where vo is the velocity it starts at and v is the velocity it ends at and t is the time it took. this is only true if acceleration is constant

Answer 2

Acceleration is defined as the change in velocity per unit of time. This means that if you velocity increases 5 m/s in 2 seconds your acceleration would be + 2.5 m/s/s. Velocity is defined as the change in position per unit time. Meaning if you moved 5 meters in the positive direction during 2 seconds, your velocity would be 2.5 m/s (assuming you are moving at a constant velocity).

If you want to relate acceleration to distance traveled you must know two of the following three other quantities, time, initial velocity or final velocity. You can use one of the following kinematics equations to calculate acceleration.

x = v0 t + 1/2 a t^2
2 a x = vf^2 - v0^2

Acceleration can also be found by using Newton's Second Law which states that acceleration is proportional to the net external force acting on an object: F = m a.

I hope one of these definitions helps.

Answer 3

i dont know really but i hope this helps


acceleration, rate at which velocity changes over a period of time ** if speed changes there is acceleration

velocity, a measure of speed in particular direction; velocity= speed + direction


i dont know theres the formula for velocity and some definitions i hope it helps , even if its only a little bit!!
